The search function is based on file names, formatted: YYmmDD_file_name.jpg
It will return files if any instance the search term is found, eg: "ark" will also return "spark", and "hark".
Multiple words can be strung together using underscores "_".
To search by a specific date, add the term: date:YYmmDD
To broaden a date search, try a shorter value, eg: to search for all works from the year 2013: date:13
By default, results are returned newest first, but to reverse this, add: order:old
The gallery will maintain search results even when an image is selected. To clear the search results, and return to the default "all images" page, submit the search with a blank text field.
